Much appreciated. I was going to get R888's...in fact priced them out yesterday and was going to pull the trigger after my next track event as I can get one more day out of my PSS.

Now I'm going to rethink this. Maybe RS3's or maybe I just stick with PSS...which are predictable and that's good for a track newb like me.

If they make the sizes you need, give the Michelin PSC (not "+" or N-spec) a try. I had great success with them on my track prep'd e46 M3, and I'm about to buy a set of F 265/35-18 and R 285/30-18 for my e92 M3. Heat cycling helps a little with the PSCs but without heat cycling I've been able to run consistent lap times starting at full depth to slight cording.
